A new approach to single-phase systems under sinusoidal and non-sinusoidal supply using geometric algebra [PDF]
, 2020 The aim of this work is to present major upgrades to existing power theories based on geometric algebra for single-phase circuits in the frequency domain. It also embodies an interesting new approach with respect to traditionally accepted power theories,

Advanced Materials, EarlyView.Melt electrofibrillation (MEF) enables the fabrication of nanofibrillar PCL scaffolds with defined architectures that guide cellular alignment and retention during cartilage tissue engineering. Unlike conventional melt electrowriting, MEF consistently directs collagen type II‐rich extracellular matrix organization, providing a tunable platform to ...

Power Extracted From Piezoelectric Harvesters Driven by Non-Sinusoidal Vibrations
, 2019 The performance of resonant piezoelectric vibration energy harvesters (RPVEHs) is strongly affected by the characteristics (shape, amplitude, spectrum, and so on) of the vibrations from which energy is harvested.

Advanced Materials, EarlyView.Mobile‐atom percolation underlying β‐relaxations fundamentally dictates the crystallization pathways of phase‐change materials. High‐frequency ultrasonic excitation dynamically modulates this critical mobility percolation network, substantially accelerating the crystallization process.

Spatial neuronal synchronization and the waveform of oscillations: Implications for EEG and MEG.
PLoS Computational Biology, 2019 Neuronal oscillations are ubiquitous in the human brain and are implicated in virtually all brain functions. Although they can be described by a prominent peak in the power spectrum, their waveform is not necessarily sinusoidal and shows rather complex ...

Nonplanar Bouligand Architectures for Enhanced Mechanical Performance in Cementitious Composites
Advanced Materials, EarlyView.Inspired by the impact region of the Mantis shrimp dactyl club, nonplanar additive manufacturing translates sinusoidal Bouligand architectures into cementitious composites. Printing‐induced anisotropy and architected interfaces promote distributed damage and arrest crack propagation, enhancing strength and energy absorption.
